Description

Technical Field

[0001] This utility model relates to the field of automated processing equipment technology, and in particular to a device for assembling an air injection valve for a puncture device. Background Technology

[0002] The assembly process of the cannula and air injection valve in the disposable abdominal wall trocar commonly used in minimally invasive surgery typically involves manually picking up the air injection valve switch, dipping it in silicone oil, placing it into the air injection valve, then manually placing it into an adhesive dispensing fixture for adhesive application before finally inserting it into the cannula. Based on practical experience, the manual assembly method has the following problems:

[0003] 1. The amount of silicone oil applied manually is uneven, unstable, and cannot be quantified. Depending on the different operating experience of different workers, the amount of silicone oil applied will also vary, which makes the assembly accuracy greatly affected by the operation process of the processing workers.

[0004] 2. During manual assembly, the fit between the two parts is tight, resulting in high labor intensity and low assembly efficiency.

[0005] 3. The inconsistent size of the air injection valve holes caused the glue applicator to slide loosely, resulting in uneven glue application.

[0006] Therefore, given the problems of low assembly efficiency and unstable assembly accuracy in the assembly process of the sleeve and the air injection valve, it is necessary to design an automatic assembly device to optimize the processing and improve processing efficiency and accuracy.

[0036] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0037] Please see Figures 1 to 4 As shown, this embodiment provides a device for assembling the air injection valve of a puncture device, including: a rotary worktable 1 suitable for rotary motion, five workstations spaced apart along the circumference of the rotary worktable 1, and air injection valve feeding assembly, silicone oil atomizing lubrication assembly, air injection valve switch feeding assembly, pressing assembly, and dispensing unloading assembly sequentially arranged around the five workstations in a one-to-one correspondence along the circumference of the rotary worktable 1. Each workstation is provided with a fixing seat 2 for positioning the main steam valve.

[0038] Based on the above, the air injection valve feeding assembly generally includes a first vibrating plate 6 that carries the air injection valve 3 and a first transfer group for transferring the air injection valve 3 from the first vibrating plate 6 to the corresponding work station; the silicone oil atomization lubrication assembly includes a silicone oil atomizer 4 and a first lifting driver 8 for driving the silicone oil atomizer 4 to move up and down. It is necessary to note that the silicone oil atomizer 4 in this embodiment is also connected to a silicone oil inlet chamber and a drive assembly for introducing silicone oil into the silicone oil inlet chamber. The silicone oil inlet chamber and drive assembly can be any mature means in the prior art, such as, but not limited to, the technical solution disclosed in CN221387051U. This embodiment does not improve the silicone oil inlet chamber and drive assembly, and therefore its structure is not absolutely limited. The first vibrating plate 6 and the second vibrating plate are used for feeding, and the specific structure and implementation principle of the first vibrating plate 6 and the second vibrating plate can be any mature means in the prior art; this embodiment does not absolutely limit this.

[0039] The air injection valve switch loading assembly includes a second vibratory plate that carries the air injection valve switch 5 and a second transfer group for transferring the air injection valve switch 5 from the second vibratory plate to the corresponding station; the pressing assembly includes a pressing mold 10 and a second lifting driver 9 for driving the pressing mold 10 to perform lifting and lowering movements; the dispensing unloading assembly includes a third transfer group for removing the assembled parts that have completed the pressing of the air injection valve switch 5 and the air injection valve 3 from the corresponding station, and a dispensing group for dispensing adhesive onto the assembled parts on the second transfer group.

[0040] The following is an example of an optional implementation, illustrated with the accompanying diagram:

[0041] First, both the first lifting driver 8 and the second lifting driver 9 employ driving cylinders. The dispensing assembly includes a dispensing rod 11 and a first cylinder 14 for moving the dispensing rod 11 closer to and further away from the third transfer assembly. The needle clamping assembly includes a needle 12 adapted for insertion into the air injection valve 3 and a second cylinder 13 for moving the needle 12 linearly.

[0042] Secondly, the first transfer group includes a first pneumatic gripper 15 for gripping the air injection valve 3 and a first two-axis motion drive assembly 7 connected to the first pneumatic gripper 15. The second transfer group includes a second pneumatic gripper 16 for gripping the air injection valve switch 5 and a second two-axis motion drive assembly connected to the second pneumatic gripper 16. The third transfer group includes a clamping pin group for fixing the assembly and a third two-axis motion drive assembly 27 connected to the clamping pin group.

[0043] Based on the above structure, it is necessary to further explain that the first two-axis motion drive assembly 7, the second two-axis motion drive assembly, and the third two-axis motion drive assembly 27 adopt the same two-axis motion drive structure.

[0044] Furthermore, the two-axis motion drive structure includes a connecting rod 17, a sliding block 18 connected to the connecting rod 17, a slide rail 19 slidably engaged with the sliding block 18, and a power structure for driving the slider's movement; wherein the slide rail 19 is prefabricated within the support base 28; the slide rail 19 has a U-shaped structure; and the power structure includes a pull rod 23 connected to the slider, and a drive motor 20 for driving the pull rod 23 to rotate. The U-shaped opening of the U-shaped slide rail 19 faces the pull rod 23. The connecting rod 17, combined with the requirements of different two-axis motion drive components, can drive the first pneumatic gripper 15, the second gripper, and the clamping needle assembly to move.

[0045] Regarding the pull rod 23 used in this embodiment, it should be specifically noted that a rotating shaft 21 connected to one end of the pull rod 23 is provided at the middle of the slide rail 19 corresponding to the U-shaped structure of the support base 28. The drive motor 20 is connected to the rotating shaft 21 to drive the rotating shaft 21 to rotate. The slider is slidably engaged with the slide rail 19 through a movable column 22. The end of the pull rod 23 away from the rotating shaft 21 is connected to the movable column 22, and the pull rod 23 is provided with an oblong through hole 24 for fitting onto the movable column 22. More specifically, taking the example of a cylindrical structure for the movable column 22, the outer diameter of the movable column 22 is preferably matched with the inner diameter of the short axis of the waist-shaped through hole 24. However, the outer diameter of the movable column 22 is much smaller than the inner diameter of the long axis of the waist-shaped through hole 24, so that the rotational motion of the pull rod 23 can be converted into the slider first making a linear longitudinal motion along the slide rail 19, and then making a linear lateral motion along the slide rail 19, or the rotational motion of the pull rod 23 can be converted into the slider first making a linear lateral motion along the slide rail 19, and then making a linear longitudinal motion along the slide rail 19.

[0046] Based on the above structure, taking the case where the slider's initial position is on one of the tracks of the U-shaped slide rail 19 parallel to the pull rod 23, when the pull rod 23 rotates under the action of the drive motor 20, the slider will first move upward along the track of the slide rail 19 parallel to the pull rod 23, and then move to the track of the slide rail 19 perpendicular to the pull rod 23. In this structure, for the pull rod 23, it first moves upward and then moves horizontally, thus realizing the movement trajectory of the pull rod 23 in two different dimensions. During the movement of the slider along the slide rail 19, the pull rod 23 always maintains only longitudinal and lateral translation, without any flipping motion.

[0047] Furthermore, it should be noted that the support base 28 is also provided with a limiting block 25 that slides with the connecting rod 17; and the limiting block 25 slides with the support base 28; the limiting block 25 is adapted to move in the support base 28 in a direction perpendicular to the connecting rod 17. The support base 28 is provided with a guide rail 26 that is adapted to the limiting block 25 in a direction perpendicular to the connecting rod 17.

[0048] In summary, regarding the device for assembling the puncture device's air injection valve in this embodiment:

[0049] The air injection valve feeding assembly delivers the air injection valve 3 to the workstation for atomization lubrication via the rotation of the rotary table 1. The air injection valve switch feeding assembly delivers the air injection valve switch 5 to the air injection valve 3, which has already undergone atomization lubrication. The pressing assembly presses the air injection valve 3 and the air injection valve switch 5 together, ensuring a reliable assembly. The adhesive dispensing and unloading assembly dispenses adhesive onto the assembled parts formed by the pressing of the air injection valve 3 and the air injection valve switch 5. After dispensing, the assembly is rotated off the rotary table 1, allowing for manual insertion of the dispensed assembly into the cannula of the puncture device. Therefore, in the assembly process of the overall air injection valve 3 and the cannula of the puncture device, the operator only needs to remove the air injection valve 3, which has already been press-fitted with the air injection valve switch 5 and applied adhesive, from the pin 12 in the adhesive unloading assembly and directly insert it into the cannula. Compared to manual operation, this not only improves assembly efficiency but also avoids the problem of manual operation being greatly affected by operator experience, thus optimizing the assembly effect. In other words, the overall operation process is significantly more efficient, saving auxiliary time, reducing labor intensity, lowering the requirements for operator experience and skills, and resulting in better assembly accuracy, stable product quality, and a significantly higher yield.
